摘要

在薄膜异质结太阳能电池领域，Cu2ZnSnS4（CZTS）是一种潜在的四元半导体吸收层。本研究采用了传统的喷雾热解方法。X 射线衍射结果证实了沉积薄膜的结构为 Kesterite。晶格参数被确定为 a = 0.5436 nm，c = 1.0856 nm。这种材料的能隙为 1.5 eV，光吸收系数超过 104 /cm。CZTS 薄膜具有 p 型性质。化学喷雾热解结束后，沉积薄膜会在热表面停留一段时间，这有助于提高结晶度。利用化学合成技术，构建了 Cu2ZnSnS4 薄膜太阳能电池。这些太阳能电池的效率为 0.5%。目前正在努力实现合理的效率水平。

Cu2ZnSnS4 Thin Film Solar Cell Construction Using Chemical Technique

Cu2ZnSnS4 (CZTS) presents itself as a potential quaternary semiconductor absorber layer in the field of thin film heterojunction solar cells. The conventional spray pyrolysis method has been used in the present investigation. X-ray diffraction results confirm the structure of the deposited films as kesterite. The lattice parameters are determined to be a = 0.5436 nm and c = 1.0856 nm. The material exhibits an energy gap of 1.5 eV and an optical absorption coefficient exceeding 104 /cm. CZTS films exhibit a p-type nature. The deposited films are kept on the hot surface for some time after the chemical spray pyrolysis is finished, which contributes to improved crystallinity. Using chemical synthesis techniques, a Cu2ZnSnS4 thin film solar cell is constructed. These solar cells exhibited an efficiency of 0.5%. Ongoing efforts are directed towards achieving reasonable efficiency levels.
